Musnad Ahmad 789:1

'Abd al-Razzaq narrated to us, Ma'mar informed us, from Matar, from 'Abd Allah ibn Buraydah al-Aslami, who said: 'Ubayd Allah ibn Ziyad doubted regarding the Basin (al-Hawd), so he sent for Abu Barzah al-Aslami. When he came to him, the companions of 'Ubayd Allah said to him: "The Prince only sent for you to ask you about the Basin; did you hear anything from the Messenger of Allah, may Allah bless him and grant him peace, regarding it?" He said: "Yes. I heard the Messenger of Allah, may Allah bless him and grant him peace, mention it: 'Whoever denies it, may Allah not let him drink from it.'"
